Though there are differences in tradition and culture from region to region, and each region has a history of its own, they form the unity or spirit of oneness that is known as world history when combined. Therefore, the study of local and world history is equally important, as they are inextricably linked and interdependent.
There is an unbroken chain by which local history is indissolubly linked with the world history. On the one hand, studying the big picture of history such as the rise and fall of civilizations, major social and economic reforms and other events affecting the entire nation, peoples and the world at large is of critical significance. On the other hand, we should bear in mind that individuals, locales and communities all played a role in shaping and being shaped by the world history. Local history can be seen as a small-scale reflection of the grand scheme of historical development as it contains a wealth of details and stories that reveal how social changes impacted the lives of ordinary people, which in turn make up the larger pattern.
Local history and the world history interact with each other since the process of history is in effect about encounters, connections, integrations and assimilations, especially in the context of globalisation. For centuries, local cultures and traditions have been invariably associated with a wide range of adaptations and assimilations in response to foreign conquests, religious conversions, new technologies, strangers from afar and overseas imported commodities. As a result, many aspects including state constitutional structures and social foundations along with policy responses to challenges and opportunities tend to be the products of local-global connections.
In short, local history and world history, despite their diversities, share a strong invisible under-current of unity that nourishes and sustains the other. Therefore, comprehending the long-run history of humanity necessitates equal emphasis being placed on both of them.
